What is an antagonist in psychology?

Antagonist. An antagonist is a chemical or drug that binds to receptors in the brain and prevents an agonist from having a reaction. Antagonists attach to the receptors in the brain and block the effect of agonists (which are chemicals that stimulate receptors and cause a response).

The antagonist can be one character or a group of characters. In traditional narratives, the antagonist is synonymous with “the bad guy.” Examples of antagonists include Iago from William Shakespeare’s Othello, Darth Vader from the original Star Wars trilogy, and Lord Voldemort from J.K. Rowling’s Harry Potter series.

Furthermore, what does agonist and antagonist mean? An agonist is a chemical that binds to a receptor and activates the receptor to produce a biological response. Whereas an agonist causes an action, an antagonist blocks the action of the agonist, and an inverse agonist causes an action opposite to that of the agonist.

People also ask, what is the difference between agonist and antagonist in psychology?

Agonist and antagonist act in opposite directions. When agonist produces an action, antagonist opposes the action. Agonist is a substance, which combines with the cell receptor to produce some reaction that is typical for that substance. On the other hand, antagonist is a chemical, which opposes or reduces the action.

Is alcohol an agonist or antagonist?

The depressant drugs are GABA agonists, acting to help GABA reduce neuronal activation more efficiently than it usually would. Alcohol also inhibits (acts as an antagonist against) another excitatory neurotransmitter (Glutamate), making it harder for Glutamate to get the nervous system excited.
